Dumped down a toilet 12 long years ago, lonely alligator Ramon resides in the city sewers, quietly eating and sleeping. In addition to feasting on the occasional stray human, Ramon devours the animal remains of a chemical plant's experiment involving growth hormones and eventually begins to swell at an enormous rate. Nothing seems to satisfy Ramon's ever-widening appetite: not all the people or all the buildings in the whole town, but he keeps trying, much to the regret of the guilt-ridden cop and lovely scientist who get to know each other while trying to nab the gator. Mediocre special effects are only a distraction in this witty eco-monster take.
